BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a baby stroller, and in particular, it relates to a baby stroller with a receiving frame and support straps for receiving a car seat.

2. Description of the Related Art

There have been strollers designed to receive infant car seats. For example, U.S. Pat. No. 6,409,205 describes “A Child's stroller including a latch mechanism for convenient folding and unfolding of the stroller, a bolster/tray that pivotally mounts to the upper handlebars of the stroller and is adapted for receiving an infant carrier or car seat for convenient transport of an infant passenger thereof in the stroller. The latch mechanism utilizes a latching handle that pivotally engages a spring loaded collar for disengagement of the stroller frame.” U.S. Pat. No. 6,478,327 describes a stroller which has “an infant carrier securing mechanism that allows the infant car carrier to be attached to the stroller and provide at least two tilt positions.” U.S. Pat. No. 7,040,694 describes an infant car seat that “can be attached to and detached from a car seat base and a stroller. The stroller can be used with or without the infant car seat. The infant car seat connects to the stroller frame through a bar that supports a tray at the front of the stroller. The tray slides out of the way for car seat attachment.” U.S. Pat. No. 4,946,180 describes “a child support apparatus for use as a safety car seat, stroller, highchair and crib. The apparatus has telescoping legs with retractable wheels and pivotable handles which may be extended to function as a stroller or retracted and pivoted to become a safety car seat. The apparatus has a restraining tray assembly adapted to receive a safety harness to provide an auxiliary safety feature that may be utilized if the harness is not fastened or accidentally comes loose from its normal male-female mating mechanism. The trays associated with the restraining tray assembly are adjustable and rotatable to provide access to the unit's seat or as an extension for the apparatus' side arms when the unit is used as a crib. The retractable wheels are adapted with telescoping legs which may be extended to allow the unit to function as a highchair.” U.S. Pat. Appl. Pub. Nos. 20090295128, 20040173997 and 20030080536 also describe a stroller that can receive a car seat.

Several stroller products on the market are designed to provide a frame for receiving an infant car seat only and cannot seat a child directly. Examples of such strollers include the Snap 'n Go Stroller by Baby Trend, the SnugRider Infant Car Seat Frame Stroller by Graco, the Universal Infant Car Seat Carrier Stroller by Kolcraft, and the Universal Car Seat Carrier Stroller by Jeep.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, the stroller 10 according to an embodiment of the present invention has a frame structure 11 with wheels attached thereto. Optionally, the frame structure 11 is foldable. A part of the frame structure 11 forms a push handle 12, which extends upwardly from the rest of the frame structure, with a horizontal portion 12 a at its top for pushing the stroller. Another part of the frame structure 11 forms a car seat receiving frame 13. In a preferred embodiment, the car seat receiving frame 13 is substantially rectangular in shape having four substantially horizontal bars (front bar 13 a, back bar 13 b, left side bar 13 c and right side bar 13 d).

A number of support straps 14 are attached to the frame structure 11 (preferably, to the receiving frame 13) and hang below the receiving frame 13. The lengths of the straps 14 are adjustable. In one embodiment, the ends of the straps 14 are threaded through multiple slits on the frame structure 11, so that a user can pull the ends to adjust the lengths of the straps. In an alternative embodiment, a buckle is provided in each strap 14 to adjust its length.

In the illustrated embodiment, two support straps 14 are attached to the front and back bars 13 a and 13 b of the receiving frame and oriented in the longitudinal direction (i.e. the direction of forward movement of the stroller), and no strap is provided in the transverse direction (i.e. the direction perpendicular to the longitudinal direction). In alternative embodiments, one or more straps may be provided in the transverse direction. The stroller 10 does not have a seat hanging from the frame for seating a child.

When a child car seat 20 is rested on the receiving frame 13, as shown in FIGS. 3 and 4, parts of the car seat 20 will contact the receiving frame 13, and parts of the car seat will be located below the receiving frame. Which parts of the car seat will contact the receiving frame 13 depends on the size and shape of the car seat; car seats of different sizes and shapes can be accommodated by the receiving frame. The lengths of the support straps 14 may be adjusted so that the straps conform to the shape of the bottom portion of the car seat 20 to provide support for the car seat. In other words, when the car seat 20 is rested on the receiving frame 13, the support straps 14 are in contact with the bottom surface of the car seat to provide support (see FIG. 3). The support straps 14 do not have any other structures, such as a storage basket, attached to it; its sole function is to provide support for the car seat.

As shown in FIGS. 3 and 4, a safety strap 15 is attached to the frame structure 11 and can be opened and closed to secure the car seat 20 to the frame structure. In one embodiment (see FIG. 4), the safety strap 15 has two straps parts 15 a and 15 b, each part being attached to the frame structure 11 at one end and having a linking mechanism (e.g., a buckle or Velcro™) at the other end for linking the two parts 15 a and 15 b to each other. In another embodiment (not shown), the safety strap 15 is a one part strap which is attached to the frame structure 11 at one end and has a attaching mechanism (e.g., a buckle or Velcro™) at the other end for attaching the safety strap to the frame structure. When the car seat 20 is rested on the receiving frame 13, the safety strap 15 may be placed over the car seat to lock the car seat to the frame structure 11 (see FIG. 4). The length of the safety strap 15 is preferably adjustable to securely lock the car seat 20 to the frame structure 11.

In the preferred embodiment, the car seat 20 merely rests on the receiving frame and the support straps 14 without being attached to or snapped into any parts of the receiving frame. This simplifies the structure of the stroller 10, and also makes it easier to place the car seat into the stroller and take it off of the stroller.

The frame structure 11 (including the pushing handle 12 and the receiving frame 13) may be made of any suitable material such as plastic, metal, etc. or a combination of such materials. The straps 14 and 15 may be made of any suitable flexible material such as fabric, plastic, etc.

It will be apparent to those skilled in the art that various modification and variations can be made in the baby stroller of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
